The study found that the main factors were a lack of human resources, high population density, lack of beds, issues with public health awareness, and problems with emergency department design. A survey of 168 medical professionals at the hospital identified health awareness as having the highest impact and lack of beds as having the lowest impact on emergency department overcrowding. The study recommends strategies like increasing staffing levels and space in the emergency department.
